Tyson, James Toback (2008)

Thoroughly engaging documentary, thanks to Toback’s inventive but lucid style, and — mostly — to Tyson himself, whose narration of his own story is by turns heartbreaking, self-aware, self-pitying, deadpan, boastful, analytical, emotional, and strange. Fully discredits the one-dimensional Tyson-as-thug theory, but doesn’t shy away from the uglier aspects of his behavior.
